The name by which this river is more generally known is St. Croix, which is probably of French origin. The original and Indian name is Mschoodiac. An intelligent Indian, belonging to the Penobscot tribe, to whom I am indebted for the signification of the original names which our rivers bear, informed me that the signification of Mschoodiac was, "Burned land river," "Open space," or "Wide prospect river," thus deriving its name from some peculiarity in the country along its borders. Probably, at some period anterior to the white man's knowledge of our Western World, a section of forest adjacent to some part of the river was destroyed by fire, originating perhaps in the torch of some invading tribe as they laid waste the wigwams of their discomfited enemies, or from the embers of the little fire kindled by the hungry hunter to cook his hurried meal. In process of time, the principal part of a forest, withered and destroyed by such a devastating scourge, would fall to the ground, opening wide prospects where densely-compacted forest trees once completely circumscribed the view. But the river may have derived its name from a circumstance of still earlier date, viz., the existence of immense fields of _meadow_ land, which abound more or less in the whole region lying about the St. Croix, often affording the voyager an unobstructed view for miles up and down the stream. In former years vast quantities of this wild grass were cut by lumbermen for the subsistence of oxen and horses during their winter operations. The St. Croix has two branches, the east and west; the latter, at its source, is contiguous to the head waters of the Machias River in the west, while the former, being of more importance and greater magnitude, stretches far to the north to the lakes, whence is its source. Of these bodies of water mention may be made of Grand Lake in particular, which is about twenty-five miles long by eight wide at its greatest extent, romantically diversified in the northern part with beautiful islands, deep coves, and far-reaching points of land, covered with dense and rather undersized trees. The shores, east and west, are composed for the most part of immense granite rocks, rising very abruptly on the southwest to a considerable elevation, covered with a heavy growth of majestic Pine, Hemlock, and Spruce-trees. Beautiful white sand beaches, which run outward with a very gradual descent for many rods into the lake, afford a most luxurious bathing-ground, where probably the young savages of former generations gamboled and indulged in aquatic sports.
